Combined oral contraceptive pills (OCPs) offer pain relief for dysmenorrhoea, though evidence is limited. Further research is needed to compare OCPs with other treatments and different OCP formulations.
Area of Science:
- Reproductive Health
- Pharmacology
Background:
- Dysmenorrhoea, characterized by painful menstrual cramps, is a prevalent condition affecting many women.
- Combined oral contraceptive pills (OCPs) are frequently recommended for managing primary dysmenorrhoea.
Purpose of the Study:
- To evaluate the efficacy and safety of combined OCPs in managing primary dysmenorrhoea.
Main Methods:
- A systematic review of randomized controlled trials (RCTs) was conducted using multiple electronic databases.
- Included RCTs compared combined OCPs against placebo, no treatment, other OCPs, or nonsteroidal anti-inflammatory drugs (NSAIDs).
Main Results:
- Seven RCTs involving 497 women indicated that combined OCPs provided pain relief compared to placebo (OR 2.01).
- Sensitivity analysis confirmed OCP benefit, reducing heterogeneity. Adverse effects like nausea and headaches were reported but not statistically significant compared to placebo.
- No studies compared OCPs with NSAIDs; limited evidence suggested potential benefit of third-generation progestagens over second-generation OCPs.
Conclusions:
- Limited evidence supports the use of combined OCPs for pain improvement in dysmenorrhoea.
- No significant differences were found between various combined OCP preparations.

Menses Phase
When fertilization does not occur, the corpus luteum deteriorates, causing a significant drop in the levels of estrogen and progesterone in the body. This hormonal decrease triggers the release of prostaglandins, which cause the uterine...
Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.
Drugs for Treatment of Diarrhea-Predominant IBS
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...
Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
